[libvirt] [PATCH] qemumonitorjsontest: Validate more commands against schema
Posted by Eric Blake 4 years, 10 months ago 
The DO_TEST() macro in qemumonitorjsontest.c was not passing the
schema through, which meant that we were not validating any of those
tests for correct usage according to the schema.

Tested by using this hack, where the test mistakenly passed pre-patch,
but correctly diagnosed the garbage post-patch:
